May the good Lord be with you down every road you roam
And may sunshine and happiness surround you when you're far from home
And may you grow to be proud, dignified and true
And do unto others as you'd have done to you
Be courageous and be brave and in my heart you'll always stay
Forever Young, Forever Young,Forever Young

May good fortune be with you and may your guiding light be strong
Build a stairway to heaven with a prince or a vagabond
And may you never love in vain and in my heart you will remain
Forever Young, Forever Young, Forever Young, Forever Young, Forever Young, Forever Young

And when you finally fly away I'll be hoping that I served you well
For all the wisdom of a lifetime no one can ever tell
But whatever road you choose I'm right behind you, win or lose
Forever Young, Forever Young, Forever Young ,Forever Young, Forever Young, Forever Young

FORE!  - Forever Young,

Forever Young...

That would be the Black Dwarf at the Heart of the Rose Nebula...

Unexplained Pattern of Cosmic Rays Discovered

ScienceDaily (July 28, 2010) — Though still under construction, the IceCube Neutrino Observatory at the South Pole is already delivering scientific results -- including an early finding about a phenomenon the telescope was not even designed to study.

IceCube captures signals of notoriously elusive but scientifically fascinating subatomic particles called neutrinos. The telescope focuses on high-energy neutrinos that travel through the Earth, providing information about faraway cosmic events such as supernovas and black holes in the part of space visible from the Northern Hemisphere.

However, one of the challenges of detecting these relatively rare particles is that the telescope is constantly bombarded by other particles, including many generated by cosmic rays interacting with the Earth's atmosphere over the southern half of the sky. For most IceCube neutrino physicists these particles are simply background noise, but University of Wisconsin-Madison researchers Rasha Abbasi and Paolo Desiati, with collaborator Juan Carlos Díaz-Vélez, recognized an opportunity in the cosmic ray data.

"IceCube was not built to look at cosmic rays. Cosmic rays are considered background," Abbasi says. "However, we have billions of events of background downward cosmic rays that ended up being very exciting."

Abbasi saw an unusual pattern when she looked at a "skymap" of the relative intensity of cosmic rays directed toward the Earth's Southern Hemisphere, with an excess of cosmic rays detected in one part of the sky and a deficit in another. A similar lopsidedness, called "anisotropy," has been seen from the Northern Hemisphere by previous experiments, she says, but its source is still a mystery.

"At the beginning, we didn't know what to expect. To see this anisotropy extending to the Southern Hemisphere sky is an additional piece of the puzzle around this enigmatic effect -- whether it's due to the magnetic field surrounding us or to the effect of a nearby supernova remnant, we don't know," Abbasi says.

The new result publishes Aug. 1 in The Astrophysical Journal Letters, published by the American Astronomical Society.

One possible explanation for the irregular pattern is the remains of an exploded supernova, such as the relatively young nearby supernova remnant Vela, whose location corresponds to one of the cosmic ray hotspots in the anisotropy skymap. The pattern of cosmic rays also reveals more detail about the interstellar magnetic fields produced by moving gases of charged particles near Earth, which are difficult to study and poorly understood.

Right now "we can predict some models, but we don't have concrete knowledge of the magnetic field on small scales," Abbasi says. "It would be really nice if we did -- we would have made a lot more progress in the field."

Since nearly all cosmic signals are influenced by the interstellar magnetic fields, a better overall picture of these fields would aid a large range of physics and astronomy studies, she says, adding that their newly reported findings rule out some proposed theories about the source of the Northern Hemisphere anisotropy.

The IceCube group is currently extending its analysis to improve its understanding of the anisotropy on a more detailed scale and delve further into its possible causes. While the newly published study used data collected in 2007 and 2008 from just 22 strings of optical detectors in the IceCube telescope, they are now analyzing data from 59 of the 79 strings that are in place to date. When completed in 2011, the National Science Foundation-supported telescope will fill a cubic kilometer of Antarctic ice with 86 strings containing more than 5,000 digital optical sensors.

"This is exciting because this effect could be the 'smoking gun' for our long-sought understanding of the source of high-energy cosmic rays," says Abbasi.

Cuneiform Tablet Uncovered by Hebrew University Team at Hazor Parallel to Code of Hammurabi

July 26, 2010, By Alex Ion

The fragments that have now been discovered, written in Akkadian cuneiform script, refer to issues of personal injury law relating to slaves and masters, bringing to mind similar laws in the famous Babylonian Hammurabi Code of the 18th century B.C.E. that were found in what is now Iran over 100 years ago. The laws also reflect, to a certain extent, Biblical laws of the type of “a tooth for tooth,” say the researchers.
